You are right.

No, users are responsible for providing a file with the required mappings.

type ?function name (e. g. ?fileMuncher) will show the help page for the 
function.

library(tkWidgets)
vExplorer()

envokes a widget that allows users to explore the vignettes of installed 
packages without having to type the code.

Why do'nt you type your code in a text editor and then cut/paste your code to R.
